4 Claims.

The invention relates generally to containers and particularly tocontainers for housing spray guns or the like.

It has been necessary in the past when painting with spray guns tothoroughly clean the gun each time after useage to insure properoperation when the gun was again used, as the paint used in conjunctionwith the guns, such as lacquer, enamel, etc., readily clog and obstructthe passages in the gun if the latter is not immediately cleaned afteruse. This is particularly true where the paint used is of the quickdrying type, wherein the paint will harden very quickly, thus cloggingthe gun in relatively short periods of non-use.

The present invention, therefore, has as a most important object theproduction of a container in which such guns may be placed when not inuse, which container is so constructed that the gun is immersed in asuitable solvent while in the container, thus preventing the nozzle andpassages from being obstructed with hardened paint.

The invention has among its further objects the production of acontainer of the kind described which is durable, efiicient andinexpensive for the purposes intended.

A further object of the invention is the construction of such acontainer in which the level of the fluid solvent is automaticallymaintained at a predetermined level.

A further object of the invention is the production of a substantiallyuniversal container in which a plurality of guns may be housed and whichis so designed as to prevent evaporation of the fluid solvent as much aspossible.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given.

To this end our invention consists in the novel construction,arrangement andcombination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like orcorresponding parts:

Fig. 1 is a side elevational view of the container with a portion of itbroken away to show the interior construction. and with an ordinaryspray gun illustrated in dotted lines; and

Fig. 2 is an end elevational .view of the container also with a portionthereof broken away to show the interior.

Broadly speaking, the invention provides a container having a portionthereof constructed forreceiving the nozzle of the spray gun, thisportion being provided with means for retaining the fluid solventtherein into which the nozzle is immersed. Also a suitable reservoir isprovided which will automatically maintain the fluid at a level tosufiiciently protect th nozzle and associated parts of the gun.

As shown in Fig. 1, the device comprises a suitable container Icomprising side and end walls 2 and 3, respectively, bottom 4 and asuitable cover 5. This container may be constructed of any suitablematerial, and as shown is preferably constructed of metal. Mounted onthe side walls 2 thereof are suitable handles 6 by means of which thecontainer may be readily transported. The cover 5 is hinged to an endwall 2 at 1, the opposite end being provided with a handle 8 by means ofwhich the cover may be raised.

Extending laterally across the interior of the container between theside walls 2 is a dividing wall I l secured to the side walls and thebottom 4 to divide the container into two fluid-tight compartments l2and I3. The wall ll is provided with notches Id of a size to receive aportion of a spray gun which is adapted to be placed in the containerwith the nozzle adjacent the bottom 6 in the compartment l2. Suitablepins l5 positioned below the notches M extend into the compartment l2and are rigidly secured to the partition wall ll. These pins are of asize to enter the paint inlet in the gun and thereby support the latteron the partition ll Positioned adjacent the end wall 2 of thecompartment I2 is a fluid container l6 supported on the brackets I!which are secured to the end wall. The container I6 is provided with aninverted port l8 which is positioned at a height above the bottom 4 toinsure a fluid level at a point above the pins l5 and above the paintinlet of the gun. Obviously, as the level of the fluid, due to theevaporation, etc., falls below 'the mouth of the port l8, suflicientfluid will flow from the reservoir Hi to maintain the fluid above themouth of th port, thus insuring sufflcient fluid in the compartment I2at all times. If several guns are put into the container at one time thedisplacement of fluid thereby might raise the level of the fluid to anundesirable height, and to relieve this difficulty the partition II isprovided with a suitable overflow hole l9 at the maximum desired level,so that the excess fluid will overflow into the compartment [3, thuspreventing any fluid from reaching the material used for the needlevalve packing.

A suitable stop 2| is provided to limit the openin; movement of thecover 5 so that the cover cannot be opened to a point where it will failto close by gravity, thus preventing any unnecessary loss of fluid dueto evaporation, etc., as the cover will always be closed except whenguns are actually being put in or taken out. If desired a spring covermay be utilized. Likewise if desired, the cover 5 may be provided with asuitable gasket (not shown) which will further seal the container,although we have found this for all practical purposes to beunnecessary.

The compartment I2 is fllled to the approximate level desired and thereservoir l8 filled and seated on the bracket II in an inverted positionas shown in Figs. 1 and 2, where ,the level of the fluid will then bemaintained at approximately the mouth of the port i8. when the gun isnot in use it is merely placed in the compartment l2 and seated upon thepin [5 as shown in dotted lines in the drawing, where the nozzle andpaint inlet and the passages therefor will be immersed in the fluid sothat there will be no possibility of the paint hardening in the gun. Itwill be noted that as the guns are supported at the paint inlet and asthe distances from the inlet to the end of the gun vary little with thesize or proportions of the remainder of the gun, the present devicereadily lends itself to guns of various sizes and shapes. When the gunis to be used again it is merely removed from the container, at whichtime it is ready for operation. Thus the usual cleaning after eachinterval of use is eliminated with a consequent saving in time. Thecontainer illustrated is designed for four guns and obviously, ifdesired, may be constructed for a greater or fewer number of guns,thereby pro viding a container suitable for any sized shop.

It will be noted from the above description that we have provided acontainer for housing spray guns when not in use in which the paintcarrying portions of the gun or guns are immersed in a suitable solvent,the level of which is automatically maintained at the proper height,which may be of a size to house a plurality of guns and designed toreduce evaporation to a Having thus described our invention, it isobvious that various immaterial modificationsmaybemadeinthesamewithoutdepartingirom the spirit of our invention;hence we do not with to be understood as limiting ourselves tojthe exactform, construction, arrangement and combination of parts herein shownand described, or uses mentioned.

What we claim as new and desire to secure by Letters Patent is:

1. In a container of the kind described comprising side and end walls.bottom and selfclosing cover, a partition member positioned in saidcontainer to form a fluid receiving compartment, a fluid reservoirpositioned in said container and having an inverted port spaced from thebottom thereof and communicating with said compartment, and means onsaid partition member for supporting a spray gun or the like with thenozzle thereof positioned in said cornpartment.

2. In a container of the kind described comprising side and end walls,bottom and cover, a partition member positioned in said container toform a fluid receiving compartment, a fluid reservoir positioned insaidcompartment and having an inverted port spaced from the bottom thereof,and a pin extending from said partition into said compartment, said pin01 a size to enter the paint inlet of a spray gun to support said gun insaid container.

3. In a container of the kind described, a fluid reservoir positioned insaid container, said reservoir constructed to maintain a predeterminedfluid level in said container, and means in said container forsupporting a spray gun, comprising a pin extending from a wall of saidcontainer, of a size to enter the paint inlet of the gun.

4. In a container of the kind described comprising side and end walls,bottom and cover, a partition member positioned in said container toform a fluid receiving compartment, a removable fluid reservoirpositioned in said compartment, said reservoir constructed to maintain apredetermined fluid level in said compartment, and means in saidcontainer for supporting a spray gun or the like in said compartment,said partition member having an overflow opening therein above saidmeans.
